“I'm captivated by Dieterich's naive but searching and intelligent narrator; the connections she ties between typography and twinning and ballet and sex are unexpected and frequently magical.I love this book.”

– Sarah Manguso, author of 300 Arguments and The Two Kinds of Decay

"It's like we're the same person. We finish each other's sentences. This is what we've been taught to desire and expect of love. But there's a question underneath that's never addressed: Once you find someone to finish your sentences, do you stop finishing them for yourself?"

As long as she can remember, Leah Dieterich has had the mysterious feeling that she’s been searching for a twin—that she belongs as one of an intimate pair. It begins with friends, dance partners, and her own reflection in the mirror as she studies ballet growing up; continues with physical and emotional attractions to girlfriends in college; and leads her, finally, to Eric, whom she moves across the country for, and marries. But her steadfast, monogamous relationship leaves her with questions she can’t answer about her sexuality and her identity, so she and her husband decide to try an open marriage.

How does a young couple make room for their individual desires, their evolving selfhoods, and their artistic ambitions while building a life together? Can they pursue other sexual partners, even live in separate cities, and keep their original passionate bond alive? Vanishing Twins looks for answers in psychology, science, pop culture, art, architecture, Greek mythology, dance, and language to create a lucid, suspenseful portrait of a woman testing the limits and fluidities of love.
